So, I updated, and it was almost trouble-free and error free. The installer did NOT put it on the taskbar as requested. Actually it DID, but then after closing that item would not work, and Windows automatically deleted it. Easily fixed. My toolbar selection came through OK this time, unlike last time. No major disruptions observed. I DO NOT SEE the "window clipping" that was mentioned elsewhere. At least, if it is present, it is not removing anything useful, no button, icon, etc appears to be reduced in size in any way. Will probably be weeks before I have exercised most features, so no clue on most yet. But nothing standard has failed so far. Still only using it on copies of the projects, but nothing jumps out at me. No problems opening the biggest projects, no odd display issues Have not looked to see if the constraints menu can be made to come up to selectable default settings, I hope that is the case. Nice to have an "undo" on the same constraint pop-up, that saves a lot of "tap dancing centipede action".
